module 'torch' has no attribute 'float8_e4m3fn'

[anlorla]

Dear developers,
I've followed all the instructions provided in the README to set up the environment and run the code. However, when I execute the relevant part （accelerate launch attacks/mist.py --cuda --low_vram_mode --instance_data_dir data/training --output_dir output/ --class_data_dir data/class --instance_prompt "a photo of a misted person, high quality, masterpiece" --class_prompt "a photo of a person, high quality, masterpiece" --mixed_precision bf16） , I keep getting the following error:
AttributeError: module 'torch' has no attribute 'float8_e4m3fn'
And the related screenshots are as follows:

Here is some information about my environment:

Could you please provide some guidance on how to resolve this issue? Any help would be greatly appreciated.

The version of torch was too low, and I reinstalled the torch-2.1.0 version to solve this problem.
